I just finished with getting my Atlantis functional yesterday.

Relay E is the sequence relay. The lit rollover activates the relay which in turn steps the sequence to the next number.

It took me a bit to get it working right. The problems I had were:

1. Dirty and misadjusted switches under the rollovers. All 3 top rollovers and the number 7 rollover.

2. Dirty rivets on the sequence stepper. I also realigned the rivets to the contacts when reassembled.

3. Dirty make break switches on score motor 3e and 4E.

I hope this helps.
